Description
Technical field
The present invention relates to a kind of portable fire-fighting fire extinguishing equipment, specially a kind of fire extinguishing that can export water mists with constant pressure
Device, and with pure water or add the water of certain proportion extinguishing fluid as extinguishing medium.
Background technology
Hand fire extinguisher now is mainly dry powder extinguisher, foam annihilator and carbon dioxide extinguisher.
Inorganic salts dry powder class extinguishing medium is filled in dry powder extinguisher.The fire-fighting principle of powder extinguishing agent includes physical
Chemically two kinds.Wherein physical principle is dry powder powderject to combustible surface, starvation, asphyxia flame.Chemistry
Property principle be that dry powder inorganic salts decompose, suppress combustion reaction free radical or active group at high temperature, make in burning chain reaction
Disconnected.Dry powder extinguisher is suitably applied conventional A classes and B class comburant fire, shortcoming is that cooling-down effect is poor, environmental pollution is big,
Post processing difficulty etc..Filled and process type extinguishing medium in foam annihilator, is sprayed using foam nozzle pressure and produces a large amount of foams,
Comburant surface is covered in, suffocate flame.Therefore, fire foam relies primarily on physical principle fire extinguishing.Foam annihilator is main
For the B class fire for putting out a fire to save life and property general, such as oil product, grease etc., but can not put out a fire to save life and property water miscible B classes fire, such as alcohol, ester, ketone, ether
Deng the fire of material, can not put out a fire to save life and property C classes fire and powered E classes fire.Filling arbon dioxide gas in carbon dioxide extinguisher.
Carbon dioxide spray from container after rapid vaporization into gas, gone out using the smothering action and certain cooling effect of inert gas
Fire.Carbon dioxide extinguisher is mainly used in the initial fire of expensive equipment, archives material, instrument and meter, electrical equipment and oils.
The extinguishing ability of carbon dioxide extinguisher is general, and under clearing, gas is easily escaped, and at higher concentrations human body is present
Asphyxiation hazard.Need now develop extinguishing ability higher, can the wider array of fire extinguisher of range of application.
Water mists are a kind of emerging high-effect fire-extinguishing technology, and the technology is using fine water fog spraying gun at elevated pressures by current
It is decomposed into diameter Dv99（Volume fraction is 99% particle diameter）Droplet less than 1000 microns is put out a fire, and fire-fighting efficiency can reach biography
5-10 times of system Water spray technology.The fire-fighting principle of Water Mist Fire Extinguishing Technique includes flame cooling, oxygen barrier asphyxia, decay heat spoke
Penetrate, kinetics function.It is additionally, since that water droplet diameter is little, mutually isolated and larger the air gap makes carefully between its droplet
The powered security performance of water smoke is greatly promoted, and is suitably applied powered E classes fire preventing and treating.
Patent 200910068755.4 discloses a kind of fire extinguisher, and the fire extinguisher is in storage compressed steel bottle under 2.5- 4MPa
Perfusion accounts for the supersaturation carbon dioxide water of storage compressed steel bottle volume 4/5.During injection, due to dissolved with gas, being atomized with separating out in water
Function, therefore enhance atomizing effect.But, the fire extinguisher does not carry out pressure regulation to pressure medium, with extinguishing chemical
Ejection, the pressure in fire extinguisher housing gradually lowers, and atomizing effect can not be effectively guaranteed, and not only extinguishing ability will be big
Big attenuating, powered security will also be significantly reduced.
Content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, there is provided a kind of constant pressure sprays the hand of water mists
Formula fire extinguisher is carried, water mists can be made to spray with the pressure of continued for constant, the atomization quality of water mists is high and stable, extinguishing ability
By force, powered safe, can solve the problems, such as that operating pressure gradually lowers with the ejection of extinguishing chemical.The fire extinguisher both can be direct
Put out a fire as extinguishing chemical by the use of pure water, and put out a fire as extinguishing chemical using the water for adding extinguishing fluid, its fire-fighting efficiency is more
Height, water stain residual are little, and convenient post-treatment is environmentally friendly, can apply to flutterring for A, B, C class, particularly E classes electrical fire
Rescue.
For solving above-mentioned technical problem, technical scheme proposed by the present invention is：
A kind of portable constant pressure water mist fire extinguisher, including fire extinguisher body, the fire extinguisher body includes outer cylinder body, trigger valve
Door and fine water fog spraying gun, are equiped with extinguishing medium in the outer cylinder body, and the fine water fog spraying gun passes through pressure hose and is located at
Siphon pipe connection in outer tube body, also includes that the inner barrel for being equiped with gases at high pressure, the inner barrel are sheathed in outer tube body, institute
State startup valve to be arranged at the opening of inner barrel, the outlet for starting valve passes sequentially through the pressure reducer and level pressure output being connected
Valve and outer cylinder body inner space, after starting valve opening, the gases at high pressure in inner core body are exported through pressure reducer and level pressure delivery valve
To constant pressure, extinguishing medium constant pressure is delivered to fine water fog spraying gun in entrance outer tube body and realizes constant pressure fine mist fire-fighting.
Further improvement as above-mentioned technical proposal：
Preferably, pressure gauge is provided with the middle part of the startup valve, the top for starting valve is provided with pressure handle, and the pressure handle is provided with
Lock.
Preferably, be provided with entrainment on the outside of the outer cylinder body, the fine water fog spraying gun be located in the entrainment and outer cylinder body it
Between.
Preferably, the gas in the inner core body is inert gas.
Compared with prior art, it is an advantage of the current invention that：
1st, water mist fire extinguisher of the invention, the gases at high pressure in inner core body enter outer tube after pressure reducer and level pressure delivery valve
In vivo, which can persistently keep constant pressure to spray, and both directly can be put out a fire by the use of pure water as extinguishing chemical, and put out a fire using adding
The water of liquid is put out a fire as extinguishing chemical, and fire-fighting efficiency is high, little, the convenient post-treatment of water stain residual, environmentally friendly, the fire that can be prevented and treated
Comprehensively, water mists spraying is stable, and Quality of fogdrop is good for type, and therefore powered security is good and stable, and extinguishing medium less residue can
